KINETOGRAPHIC CAMERA. v

SPECIFICATION forming part of Letters Patent No. 645,477, dated March13, 1900. Application filed October 14, 1899. 'Serial No. 733,671. (Nomodel.)

.To @ZZ whom it may concern:

Be it known that we, FREDERICK MAR- SHALL LEE, a resident of Oaktield,Waltonupon-Thames, county ofSurrey, and EDWARD RAYMOND TURNER, aresident of Lynwood, Queens road, Hounslow, London, county of Middlesex,England, subjects of the Queen of Great Britain and Ireland, haveinvented certain new and useful Means for Taking KinematographicPictures,(for Which we have applied for a patent in Great Britain, No.6,202, dated March 22, 1899,) of which the ollowin g is a specification.

The'object of our invention is to produce kinematographic pictures insuch man ner that they may be exhibited in the colors of the originals.

According to our invention we place between the object and thesensitized surface on which the pictures are to be taken thecolor-screens which are used in taking negatives for reproduction incolors, the said color-screens being mounted so that they are rapidlyand in succession brought into position as each successive portion ofthe film is brought into position to receive the photographic picture.Positives (termed colorrecords from the negatives thus taken may beexhibited through a like moving screen, and the several picturescorresponding to the different color sensations being exhibited rapidlyone after the other present to the eye an appearance in form, movement,and color resembling the original from which the photographs were taken.The positives of the various color sensations may be exhibited singly inrapid succession, or tWo or more of them may be superposed.

In the accompanying drawings we have illustrated arrangements accordingto this invention, with reference to which we Will describe the man nerin which the invention may be carried into practical effect; but We donot limit ourselves to these precise arrangements.

Figure l is a vertical section showing the apparatus for taking thenegatives; and Fig. 2 is a face view, on a reduced scale, of the screenthrough which the negatives are taken.

Referring first to Fig. l, A is the camera in which the kinematographicilm d, on which the negatives are to be taken, is exposed before anopening o2 behind the lens A2. This may be arranged and operated in theusual manner. Mounted in bearings b is a shaft b2, having secured to ita bevel gear-wheel b3, gearing With a bevel gear-Wheel a3 on the axis ofthe sprocket-Wheel a4, which is one of the ordinary sprocket-wheels byWhich the film a is moved. l The shaft b2 has secured to it thecolor-screen B, (shown separately in Fig. 6o 2,) 'provided with thethree colored glassesviz., a red glass R, a green glass G, and ablue-violet glass B V. The parts at c are opaque, and by making theseopaque portions greater or less in width the exposures for the severalphotographic negatives are regulated. The wheels a3 and b3, Fig. 1, areso proportioned that a glass of the color-screen is brought intoposition by the rotation of the disk B each time a fresh portion of thefilm is exposed at the opening @L2-that is, the disk B is rotated oncefor each three portions of film exposed, the opaque portions c shuttingoft the light as the margins of the color-records pass the aperture co2.The upper part of the 75 disk B is shown as being inclosed in alightexcluding hood d, or other provision may be made for the exclusionof light. In place of' arranging the screen B inside the camera betweenthe opening a2 and the lens vA2, as shown, it may be arranged outsidethe lens, as shown in dotted lines.

In exhibiting positives made from negatives taken in an apparatus suchas above set forth the light passing through a view on the 8 5 filmshould also be made to pass through a glass screen of the same color asthe screen through which the light passed in the production of thenegative.

In referring to the screen hereinbefore and in the claims We of courseinclude in the expression glass any material sufficiently transparentfor the purpose.

Having now particularly described and ascertained the nature of thisinvention and in 95 what manner the same is to bepert'ormed, we declarethat what we claim isl. In a camera for taking kinematographic negativesa color screen or shutter placed between the object and the sensitizedsurface roo rotating the said disk synchronously with the movements ofthe sensitized surface.

In testimony whereof we have signed this specification in the presenceof two subserib- I5 ing witnesses.
